ATMOSPHERIC CONDITIONER FOR ROOMS.

Application filed August 15, 1924. Serial No. 732,343.

My invention relates to improvements in atmospheric conditlonlng means for storage and otherrooms.

An object gof the invention is to provide means of the present naturefor circulating air in and ventilating 'a irhom and at the same time effecting that temperature within the room desired for'the particular use to which the room isemployed, said means being of simple, durableand inexpensive construction and adapted to operate efficiently, not only durin theactive employmentofa. ecting medium in connection temperature a v therewith, but afterwards by reason ofiholding over capacity inherent in said means.

With the foregoing and other objects in view, which will appear in the following description, the invention resides in the novel combination and arrangement of parts and in the details of construction hereinafter described and claimed.

1n the drawings, Fig. 1 is a longitudinal,

central, sectional view of an atmospheric;,; conditioner embodying my invention, a room;

in which the device is installed being represented in said Fig. 1 and Fig. 2 is a hori-j' zontal sectional view taken through the up-' per portion of the device as on the line 2-2 of Fig. 1.

Referring to the drawings, wherein like reference characters are used to designate similar parts, it will be observed that myimprovement includes two upright ducts 15.,15'

arranged side by side. Theseducts A,' B pass through the bottom of a tank G and are carried bysaid tank, which,"in turn, i

supported on a shell-like base a. Theitan 1 and duct assembly, above described,'is installed in a room D, the base 0 resting on the floor 11 over admin 12 therein. A feed pipe 13 fitted with a valve 14, is led intothe tank G and supplies the same with water i or other temperature transmitting and hold- 'ing fluid. A drain pipe 15 leading from the upper portion of the tank C downwardly through the bottom 10 thereof and into the drain '12 limits the high level of the water within the tank C. Reaching through the tank C as shown, substantial portions of theducts A, B, medially thereof, are submerged in the water. Coiled about the duct A is a pipe E for a temperature afiecting'medium, the turns of the pipe being. spaced apart from each other and from said duct A, said coiled pipe E having a feed branch 16 and a return branch 17, as shown. Capping the tank 0 is a cover 0' through which the ducts A, B and pipe branches 16, 17 extend,

the room D near the floor 11 thereof and is fitted with a damper 18. The upper end of said duct A opens into the outer air above the room, the upper portion of said duct be- The lower end of the duct A opens into ing supplied with a branch-duct a fitted with a removable plug 19 and also with a damper 20, both within the room. The upper end of the duct B opens into the room near the ceiling 21 thereof, the lower end *either event, a suitable refrigerating medium is conducted into and through the turns-of the coiled pipe .E with the result that the water within the tank C is cooled toa low degree and the air within the ducts A, B refrigerated through the medium of the chilled water. With the dampers 18, and open and the plugs 19, 22 and 23in place, fresh air settles from without into the duct A where it is refrigerated and from whence it flows into the lower ortion of the room.

Rising adjacent the wa s of the room said 'air reaches the upper stratum therein from whence it is drawn downwardly through the duct B and expelled to the outer air through the branch duct 6 Such down drafts in the ducts A, B are brought about by reason of the effect of the cold water about said ducts, which, as above stated is chilled by the refrigerant in the coiled pipe E. Closing the three dampers 18, 20 and 25 and removing either ofthe plugs 22 and 23, or both, and the plug 19, results in refrigerated circulation of air within the room, while the opening of all of said dampers accompanied with the removal of either of said plugs 22,

23, or both and the removal of the plug 19,

results in mixed refrigerated ventilation and internal circulation of air within the room. With a heating-medium flowing through the coiled pipe E ventilation and internal cirentering duct B from the room or from without, or both, aiid having egress from duct-A into the room or to the outside thereof, or both, according tothe use that is made of the dampers 18, 20 and and the plugs 19, 22 and 23. f

Greater efficiency under heating is obtained by placing the coiled pipe E about the duct B, and, where the principal need is for heating, I so place said pipe E. In this connection, I wlsh it to' be understood that Where the need for both heating andvfor refrigeration obtains and where the expense of the temperature affecting medium employed must be considered, I employ a coiled ipe about each of the ducts A, E,'the pipe a out the duct A being used as a conduit for a refrigerant and the pipe about the duct B for a heating medium. Whether refrigerating Or heatin the air within the ducts A, B is afi'ected, t rough the medium of the water or other fluid in the tank C, and said fluid being of substantial uantity, holds over orzcarries on the action ot the device for a considerable period after cessation of the flow of temperature aflectin medium in the-pipe E. This feature is a vantageous in that it prevents rapid changes of temperature or stagnation of the atmosphere within a room, when the normal operation of the device has been interrupted. i

Changes in the specific form of my invention, as herein disclosed,'may be made withspending end of theother duct communicatwith the outer air at said lower portion of the room, the upper ends of said ducts communicating respectively with the outer air and with the interior of the room at its upper portion, a tank for a temperature holding and transmittin fluid through which said ducts pass, an a conduit for a temperature affecting medium, said conduit bein immersed in said fluid and closely encirchng one of said ducts.

2. An atmospheric conditioner for a room comprising two adjacent upright ducts, one duct opening at the lower end thereof into the interior ofthe room near the floor and the second duct opening at its upper end into the interior of the room near the ceiling, said first duct having valved communication at its upper end with the outer air and with the interior of the room near the ceiling and the second duct having similar communlcation at its lower end with the outer air and with the interior of the room near the floor, a tank for a temperature holding and transmitting fluid through which said ducts pass and a conduit for a temperature affecting medium immersed in the fluid in said tank and coiled about one of said ducts, the turns of the coils of said conduit being spaced apart from each other and from the duct encircled thereby,

3. In an atmospheric. conditioner for a room, two adjacent upright ducts, one for'r taking in fresh air' from above and deliver ing it into the room near the floor, the other ceiling and exhausting it into the outer air from below, a tank'for a temperature transmitting fluid, said ducts passing through said tank and the fluid therein, and a conduitfor a refrigerating medium immersed in the fluid 1n sald tank and arranged in near proxlmlty to saldfirst duct.

'for taking oif air from the room near the 1 In testimony whereof, I have signed my name to this specification. K
